Patented May 14, 1935 UNITED STATES COMBINATION WEATHER-STRIP AND WINDOW FRAME r 12 Claims.

My present invention relates to certain new and useful improvements in combination weather-stripping and. Window frames, where there is free opportunity to open the windows and tilt the same inwardly without dismantling the weather-strips, and where the windows can be readily closed and the weather-strips restored to absolutely weather tight position as before. An object to be mentioned among many is to permit the use of metal weather-strips which will act as cooperative guides as well as weather-stripping, and also by pivotally arranging the retaining strips or portions thereof in the window frames the window sashes may be swung inwardly for cleaning purposes and then restored to normal position in a solid weather tight manner without the difficulty and expense of employing ordinary supplementary weather-stripping which is often complicated and expensive. And the invention may therefore be said to consist essentially in the construction, combination, and arrangement of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawings illustrating my invention:

Figure 1 is a front elevation of a window frame built to embody the several features of my new invention and shows the weather-stripping com bined therewith, the window sashes being shown as closed.

Figure 2 is a vertical section of the same on the line 2, 2, of Figure 1.

Figure 3 is a similar vertical section, showing the window as open with its pivoted strips and sashes tilted inwardly. I

Figure 4 is a cross-section on the line 4, 4, of Figure 2.

Figure 5 is a cross-section on the line 5, 5, of Figure 2.

Figure 6 is a sectional partial plan broken away and taken on the line 6, 6, of Figure 3.

Figure '7 is an enlarged detail view of the upper ends of the strips on the inner sash and inner retaining strip.

Similar characters of reference designate corresponding parts in all the different figures of the drawings.

I denotes an ordinary rectangular window frame of theconventional type, having the vertical inner opposing channels 2 and 3 on each side for the window sashes 4 and 5, said channels being thus divided into the two usual guideways for the two sashes 4 and 5 by means of the outer retaining strip 8, the inner retaining strip 5 and 6 and the middle parting strip 1 and 1*. Any or all of these retaining and guiding strips may be made integral with the frame l, or they may be made separate and detachable, both channels 2 and 3 on the opposite sides of the frame being made in the same manner. In the present example of the invention the middle parting'strip is made of two parts i and l the meeting or adjoining ends of strips 1 and l being beveled or chamfered at 1* Where they engage each other near the middle of the vertical length of channels land 3. The upper pieces I are secured rigidly in channels 2 and 3, while the lower pieces i are loose and pivoted at their lower ends at?! in the lower ends of channels 2 and 3, so that they may occupy a position in vertical alignment with parts i, as shown in Figure 2, and at other times may be tilted downwardly and inwardly, as in Figure 3. The same bisectional construction is true of the inner retaining strip which consists of two pieces 6 and 6 the pieces 6 being fast in the frame and pieces 6 being hinged at their lower ends at 6. The adjoining meeting ends of strips 6 and 6 are beveled at 6*. Thus pieces 6* may occupy the vertical or the tilted positions. And they function with the sash 5, as the strips l function with the sash 4, as shown in Figure 3.

To the sashes 4 and 5 metal bars 9 and ID are pivoted at 9 and lfl Chains 9 .and Ill are fastened to the bars '9 and II]; and these chains also connect with the sash weights 9 and "l said chains running over pulleys in the upper end of frame and supporting the weights in the usual receptacles in the frame, as shown in Figure 3. These window sashes 4 and 5'both have a rounded portion 4 and 5 usually small, see Figure 6, at their lower ends to enable the windows to more easily swing inwardly, as shown in Figure 3, these round places being at each end of the sash.

To the opposite vertical edges of' the outer or top window sash 4 are secured by screws or otherwise angular or -shaped metal guides ll, or which the bent angular part Il straddles or encloses the dividing strips 7 and l and as the sash 4 is raised or lowered the guides I! on the respective edges of the sashes t ride up and down on, these dividing strips. The way the guides l1 engage strips 1 and l is brought out clearly in Figure 4.

,On the opposing vertical edges of the lower or inner sash 5 are secured by screws or otherwise a metal strip l6, having a portion along one of its longitudinal edges bent over on itself at It to thicken a part of the plate and form a guide for the flange |5 of the right angled metal strip Hi, the angular member l of which is secured to the pivoted inner retaining strips 6*. These parts are clearly portrayed in Figures 4, 5, and 7.

The strip l5 is received into the guide formed sash 5 is raised and lowered. At the upper end of flange I5 of strip I5 is a slot l5 whichcooperates with a pin i6 on the metal strip l6. Said slot and pin connection is for the purpose of enabling the side strips 6 andthe window sash 5 to be held more securely together when they are swung inwardly as shown in Figure 3 for the purpose of easy access for cleaning and other purposes, for it will be seen that whenthe strips 6* and the sash 5 are alongside of each other, the sash 5 being down in the closed window position, the flange, i5 engages behind the strip l6 and the slot receives and engages pin 16 to hold the "parts together when the strips 6 turn on their pivot pins 5. V p

' On each strip 6 is mounted a locking device consisting of a slide l I having a handle M. The slide H is held by screws l2 that work in a slot I3, and by laying hold of the thumb pieces M'the slides l i can be moved up and down. When they are pushed down below the position shown in Figure 3 into the lower position shown in Figure 1 they will embrace the joints at 6' where the ends of strips 6 and 6 are in contact, so that the strips 6 are locked to strips 8 and cannot be let down into the position shown in Figure 3. When the locks I i are raised into the position in Figure 3, they are released from the strips (5 and they can be swung down on their pivots at 6 into the lowered position in Figure 3, carrying with them the sash 5, which will then be, inposition for cleaning or such other attention as it may'need. It will thus be understood that the metal strips i7, i5, and H5, arranged in the way I have described constitute effective weather stripping which are'closely and tightly fitted to keep out cold air and storm. But theuse of these tight pieces does not'interfere with the movement of the windows when they require to be tilted or swing inwardly for cleaning and other purposes. The windows can be opened or closed at any time, and tilted at any time, and yet the weather-strips are not disturbed in such a way as to impair their efiiciency or value. I

The operation and use will be clearly understood from the foregoing description of the construction and application of the different parts.

Many changes in the arrangement and combination maybe made within the terms of the claims Without departing from the invention and I reserve the liberty of readjusting the parts to meet the requirements of individual cases. My improved device can be easily applied to existing window frames by dividing the middle and inner retaining strips at or near the center with angular cuts and substituting pivoted strips insteadof the lower half of each inner strip.
